Be it known that L 'CARL P. Baioomvinf, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented. certain new and use"- iul I-DIPIOVGIDBHtS in Oil circulatzing Sys tems, of which I declare the following to he a full, clear, and exact description;

This invention relates to a svstem for automatically circulating oil to the parts of an internal combustion engine requiringhd'irication.

One object of the invention is to pro vide a simple, inexpensive, and positive means of propelling oil from the reservoir in the base of the crank case to the por tions of the engine needing lubrication.

My invention is an inrpti vemerrt over old methods o'i circulating oil by splashing; in that the oil is given a positive thrustby a paddle in a restricted passage" whereby the oil is conveyed to an auxiliary trou l froinwhieh a splashing: member attached to the piston rod propels the oil to" the-desired portionsof. the engine.

Another object of the invention is to furnish means for e'fi icientlw lubricating the engine with a limited amount of oil n' the crank case, and to" at all times maintain a thorough circulation of oil through the c 'an'k case, thus hoe the oil h o nogene' one, and veooll- (hi-her objects and advantages relating to details oi construction and econoni ies of manufacture will appear as I. proceed with the description of that emu bodiment of the imvcntirm, which iior the purposes at the '[n'eseut application I have illust ated in the accompairy hig drawings Figure I is a vertical sectional view ot one form of my invention;

Figure 1 1 is a; vertical sectional View at right angles to Figure I, and taken along the line ILL-11 of Figure L-loolring int'he direction indicated by arrows.

In Figure L the casing: 1 houses the eranl'e 2 jouruailed in the casing; Upon crank is supported the piston 1 061 8, having. are paddle 4 extending t rom one' end and reaching: through the slotted partition or trough 5 Which has the sections 6, 6 for retaining oil serving as: an auxiliary reservoir above the main reservoir 7 in the base of the casing. Between the paddle 4, and the crank 2, is the multiple prong splasher 8, dipping into the oil in the trougl'l. 5, for

splashing the oil into the up er portion of the casing for lubricating the piston and the Various bearings. At the bottom of the trough 5 is provided the annular channel 9 having a slot 10 connectin it with the upper side of the trough; am havin the passageways 11 communicating with the reservoir 7 in which the channel is partly submerged.- In. the sides of the trough 5 are arranged the passageways 12 for draining excess accun lation of oil;

The operation is as follows The crank 2 on rotating 6 meets the lower end of the piston rod together With the paddle at in a circular path so that the paddle assumes the position shown in dotted hues in ure' 1, beginning the right hand side of the -figure in the position shown, dipping down into the channel 9 as the cycle pro grosses drawing? in oil through the perform t-ioris 11,- and irnpel'li-ng oil toward the left handend of the charmer where it spi s over the edge of the channel and into the trough where the diverging walls of the trough cause the oil to a cumulate in the pat-h of the prongs 8 so that the oil thus accumuated' is plaehed in the subsequent cycle. k

The passageways; or perforations- 12 low the oil to'drain to a fixed level thus preventing an excessive accumulation of oil in: the trough 5, as Well providing a means for continually circulating the oil; since the oil returning from the .s] lashi11g oi the bearings passes largely down the lh'isidii" trails of the casing 1, then. down from the edges ofthe trough 5, and through the perforations l2,'while fliSl') oil from the reservoir Pilitlttdl into the trough by the paddle 4 In the above n'i'anner the" oil is given .1 continuouscirculation, whereby the entire quantity of oil in the reservoir is utilized, and pockets of stagnated oil are avoided.-

The' active circulation or the oil from the to the reservoir 7', maintains" the oil' at uniform moderate temperature by vi'rtueo't' the cooling derived from the walls of the casing. V

I am aware that the particular embodiment of my invention above described and illustrated in the accompanying drawing is susceptible of considerable variation without departing from the spirit thereof and therefore I desire to claim my invention broadly as Well as specifically as indicated by the appended claims.

I claim as my invention:

1. In a lubricating system for an internal combustion engine, a casing, a crank journaled therein, carrying a piston rod, a main reservoir, and an auxiliary reservoir above said main reservoir, means attached to said piston rod for lifting oil from said main reservoir into said auxiliary reservoir and simultaneously splashing oil from said auxiliary reservoir for lubricating the engine.

2. I11 a lubricating system for an internal combustion engine, a casing, a crank jour naled therein, a piston rod supported on said crank, a" slotted trough having a section to retain oil, an extension on said piston rod including a paddle reaching through said slot for lifting oil to fill said trough, and a splasher for throwing oil from said trough for lubricating said engine.

In a lubricating system for an internal combustion engine, a casing, a crank journaled therein, a piston rod supported on said crank, a slotted troughhaving a section to retain oil, an extension on said piston rod including a paddle reaching through said slot for lifting oil to fill said trough, andv a multiple prong splasher for throwing oilfrom said trough for lubricating the engine.

4. In a lubricating system for an internal combustion engine, a casing, a crank journaled therein, a piston rod supported on said crank, a slotted trough having a section to retain oil, an extension on said piston rod including a paddle reaching through said slot for lifting oil to fill said trough, and a splasher for throwing oil from said trough for lubricating said engine, said trough having overflow means for draining excess accumulation of oil.

5. In an internal combustion engine, lubricating means including a casing having a reservoir in its base, a crank journaled in said casing, a piston rod supported upon said crank having a paddle extending therefrom, a slotted trough supported in said casing above said reservoir, said paddle travelling through said slot for propelling oil from said. reservoir into said trough, and additional means extending from said rod for splashing the oil deposited in said trough, whereby the splashed oil is circulated to the portionsof the engine to be lubricated. I

G. In a lubricating system for an internal combustion engine, a casing, a crank journaled therein, a piston rod mounted on said crank having oil propelling means at one end, a reservoir in the base of said casing, an annular channel partly submerged in said reservoir having a slot in one of its walls, and passageways in certain of its walls communicating with said reservoir, an auxiliary container above said reservoir between the ends of said channel, said container having upwardly diverging walls with overflow passageways for draining excess accumulation of oil from said container, said propelling means elevating oil from said reservoir to. said container, and auxiliary means mounted on said piston rod above said propelling means for splashing oil from said container to lubricate the engine.

7. In a lubricating system for an internal combustion engine, a casing, a crank journaled therein, a piston rod mounted on said crank having oil propelling means at one end, a reservoir in the base of said casing, an annular channel partly submerged in said reservoir having a slot in one of its walls and passageways in certain of its walls communicating with said reservoir, a
